In order to research the relationship between falling off of young apricots fruits and temperature，comparative study on different cultivations of apricots under different temperatures was conducted.Analysis was made on the local productions and meteorological data in the past five years，figuring out the temperature ranges of open field and facility cultures.After a comparative study on these ranges，the preference temperature range，sub-preference temperature ranges and dangerous ranges for the cultivation of apricots at the stages of florescence phase，low-temperature sensitive phase and the phase of first fruit dropping were proposed.Specifically speaking，the preference temperature ranges were from 1.9-7.5 ℃ to 10.3-18.6 ℃ at the florescence phase，from 3.1-7.9 ℃ to 13.1-18.8 ℃ at the low-temperature sensitive phase and from 4.1-10.4 ℃ to 15.0-23.9 ℃ at the first falling-off phase of young apricots，with the percentages of days of 57.5% and 50.0%，66.7% and 63.3% as well as 60.0% and 60.0% respectively.It was suggested that the percentages of days of preference temperatures at different phases should be greater than or equal to 60%，with 5.8%-10.0% for sub-preference temperatures and less than 10.0% for dangerous temperatures.
